The best I can tell, the part of the article you've quoted is a reference to Finland's welfare policy in general, not this experiment. Note that it follows "a reflection of public discomfort with the idea of dispensing government largess free of requirements that its recipients seek work". Just bad writing, I think. But I can't find any other sources that back up the idea that they're changing this project mid flight, which would be a really bizarre thing to do, since it would completely invalidate any possible results.
